Today, researchers from the University of Michigan have unveiled an exciting new development in laser technology: a tiny but powerful laser that can fit on the tip of a human finger! This “shrunken” laser can produce a beam of light that is almost a thousand times more powerful than traditional lasers, making it an incredibly useful tool for a variety of applications. The researchers achieved this impressive feat by using a special nanostructured material that allowed them to shrink the size of the laser without sacrificing any of its power or efficiency. The possibilities for this breakthrough are endless, and it could revolutionize the way we use lasers in the future.
